COOLERV FOR `lVIIL-K-CANS.

SPECIFICATION forming part of Letters Patent N o.. 659,150, datedl October 2, 1900.

Application led August 2, 1900. b'erial No. 25,700. (No modeL v To all whom 2S-may concern:

'Be itknown that I, ROBERT B. KING, actizen of the United States, residing at Bristol;

in the county of Bucks and State of Pennsyl.

vania,haveinvented new and useful Improvements in Coolers for Milk-(lans, of which the following is a specification.

My invention relates to improvements in that type of milk-.coolers which are designed to rest in the mouths of milk-cans and serve the additional purpose of Stoppers therefor.

It consists in a certain peculiar construction the novelty, utility, and advantages of which will be fully understood from the following description and claim when taken in connection with the annexed drawings, in which- Figure l is a diametrical section'illustrat ing myimproved cooler in its operative posi` tion in the mouth of an ordinary milk-can. Fig. 2 is a perspective View of the body of the cooler, and Fig. 3 is a' similar view of the cover thereof.

In the said drawings similar letters of reference designate corresponding parts in all of the views, referring to which- A is a milk-can having a body abreast b, a neck c, and a mouth d, and Bis my improved cooler,which comprises a body C and a cover D therefor and is preferably formed of the same kind of metal as the can. The body C of the cooler is circular in form and is slightly tapered or gradually reduced in diameter toward its bottom in order that it may be wedged in the mouth of the can to tightly close the same. It is provided at its upper edge with a bead c, which contains a stiffening and strengthening wire f, and is also provided with two bayonet-ways g, the said ways comprising vertically-disposed portions h, formed by pressing the bead e and wire f therein outwardly, as best shown in Fig. 2, and horizontally-disposed portions c', formed by pressing the side wall of the body outwardly, which horizontally-disposed portions c' are also disposed in opposite directions, as illustrated. The cover D of the cooler comprises a cap j, a flange lo depending therefrom and tapered in conformity to the body C in order to effect an air-tight closure thereof, and a handle l, which is disposed above and connected at its ends to the cap. Said cover is provided at diametrically-opposite points on its depending flange k with protubc-rances m, which are preferably formedy by rivets clenchedand soldered to the inside of the flange, as indicated b vfn in Fig. 1, and are designed to operate in conjunction with the bayonet-ways g of the body'C to secure the cover therein in an air-tight manner.

In using myimproved cooler a small quantity of ice is placed in the body O thereof, and the cover D is placed in the upper end of the body, with its protuberances m coincident with the vertical portions h of the bayonet-ways g, and is pressed downwardly to close the cooler in an air-tight manner, and is then partially turned to carry the said protubera nces into the horizontal portions t of the bayonet-ways and securely fix it in the body. The cover D is'Y pressed downwardly and turned in the body C through the medium of the handle Z, which also serves to facilitate placing the cooler in and removing it from the mouth of the milk-can.

When the cooler, with a small quantity of ice therein, is placed and pressed downwardly in the mouth of the can, it serves to effect a tight closure of the same and also to keep the contents of the can in a cool and wholesome condition, this latter being due to the fact that the cold air from the ice in the cooler descends through the milk in the can. Owing to the air-tight closure of the cooler a small quantityy of ice will last therein for a considerable length of time and serve to keep the milk in the can in a cool and wholesome condition.

The cooler is preferably of the proportional size illustrated, and hence takes up only about one-twentieth part of the capacity of the can. It is also advantageous to have the cooler of the proportional size illustrated, for it will be seen that it may be handled-t1 e. placed in and removed from the mouth of a can-with the same facility as an ordinary can stopper or cover. It will also be seen that by virtue of its having the handle and being adapted to be closed in an air-tight manner the cooler is susceptible of being used to advantage as a receptacle for carryingice from place to place.

lt will be appreciated from the foregoing that my improved cooler, notwithstanding its advantages, is very simple and may therefore be produced almost as cheaply as the IOO ordinary can-cover. It will also be appreciated that While the cover D may be quickly and easily secured in and removed from the body C ofthe cooler there is no liability of its being casually disconnected from said body incident to the handling of the cooler or the placing of the same in or the removal of the saine from the mouth of a can.

I have entered into a detailed description of the construction and relative arrangement of the parts ot' my improved cooler in order to impart a full, clear, and exact. understanding of the same. I do not desire, however, to be understood as con fningmyself to such specic construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claim.

Having described my invention, what I claim, and desire to secu re by Letters Patent,

The combination with the milk-can having the neck c and the mouth d; of the removable, combined cooler and stopper consisting essentially of the body adapted to contain ice, and tapered or gradually reduced in diameter toward its bottom whereby it is enabled to snugly occupy the mouth and tightly engage the neck of the can, and having the oppositely-disposed bayonet-ways adjacen t to its upper edge, and the removable cover for the body having the handle Z, and also having the depending flange tapered in conformity to the body and of a diameter to snugly fit into the upper portion thereof, and the exterior protuberances` on lsaid flange adapted to enter the bayonet-ways of the body, whereby it is necessary in connecting the cover to or disconnecting it from the body to move said cover vertically and partially turn the same, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ROBERT B. KING.
